Space systems. Lithium ion battery for space vehicles. Design and verification requirements. | Status: Superseded, Withdrawn

1 Scope This International Standard specifies design and minimum verification requirements for lithium ion rechargeable (including lithium ion polymer) batteries for space vehicles. Lithium ion secondary electrochemical systems use intercalation compounds (intercalated lithium exists in an ionic or quasi-atomic form within the lattice of the electrode material) in the positive and in the negative electrodes. The focus of this International Standard is on “battery assembly” and cell is described as “component cells” to be harmonized with other industrial standards and regulations. “Performance”,” safety”, and “logistics” are the main points of view to specify. This International Standard does not address “disposal” or “recycle”; however, some recommendations regarding disposal are suggested.

1.1 Life cycle

The service life of a battery starts at cellactivation and continues through all subsequent fabrication, acceptance testing, handling, storage, transportation, testing preceding launch, launch and mission operation. The scope of this International Standard addresses the shelf life, from cellactivation to launch, although the life design and evaluations of the battery on the ground need to accommodate to the whole mission life in space. Each article in this International Standard addresses “performance”, “safety”, and “logistics”, according to the each stage of lifecycle.

NOTE Stages 3 and 5 include storage period which induce some performances verifications.
